Tenant can terminate every 3 years, landlord needs grounds
The tenant can terminate a commercial lease at the end of each 3-year period by giving 6 months’ written notice via registered letter or bailiff notification. No reason is needed and no compensation is due. The landlord can only terminate under specific legal grounds (personal use, major works, serious breach), and compensation may apply.
Belgian commercial lease law, governed by the Commercial Lease Act of 30 April 1951, provides strong protections for commercial tenants. The standard lease runs for 9 years, divided into three 3-year periods.
The tenant’s right to terminate at each triennium (3-year mark) is absolute and cannot be waived in the lease. Any clause restricting this right is considered null and void. The 6-month notice period must be respected strictly.
The question of whether a commercial lease can be terminated before 9 years is one of the most common in Belgian commercial rental law.
Termination procedure
For the tenant (at 3-year intervals):
- Calculate the deadline: 6 months before the end of a 3-year period
- Send registered letter or arrange bailiff notification
- State clearly that you are terminating the lease
- No reason needed — no compensation to pay
For the landlord (at any time, with grounds):
- Identify valid legal grounds for termination
- Send registered letter or bailiff notification at least 1 year before the proposed end date
- Specify the grounds clearly and in detail
- Pay compensation if applicable (1-3 years of rent depending on grounds)

Landlord termination grounds and compensation
| Ground | Notice period | Compensation to tenant |
|---|---|---|
| Personal use by landlord or family | 1 year | None (if actually occupied within 6 months) |
| Major renovations (cost > 3 years’ rent) | 1 year | 1 year’s rent |
| Serious tenant default | Immediate (via court) | None |
| Change of destination (different use) | 6 months (at triennium) | Up to 3 years’ rent |
| Without grounds (at triennium only) | 6 months | Up to 3 years’ rent |
If the landlord claims personal use but does not actually occupy the premises within 6 months, the tenant is entitled to compensation of up to 3 years’ rent. This rule prevents abuse of the personal use ground.
A mutual termination agreement is always possible at any time. However, be cautious about signing such agreements without legal advice — commercial tenants often have stronger rights than they realize. The right to lease renewal is a valuable right that should not be waived lightly.
Regional specifics
Brussels-Capital Region
Commercial lease law is federal, so the rules are the same across all regions. In Brussels, the commercial courts have extensive experience with commercial lease disputes and tend to apply the law strictly in favour of tenant protections.
Wallonia
The same federal rules apply. Walloon courts are generally protective of commercial tenants, especially regarding the requirement for landlords to prove the reality of claimed renovation works before obtaining termination.
Flanders
Flemish commercial courts apply the same federal law. Flanders has seen increased litigation around the “major renovations” ground, with courts requiring detailed and credible renovation plans before authorizing termination.
